Hy先， 我尝试通过SSH连接到本地网络中的MySQL数据库但是他说他想在我的计算机上打开该数据库。
使用方法验证用户'root'的主机'mysqldatabase' 'mysql_native_password'因消息失败：用户拒绝访问 'root'@'mymachine'（使用密码：YES）---＆gt; MySql.Data.MySqlClient.MySqlException（0x80004005）：拒绝访问 用户'root'@'mymachine'（使用密码：YES）
问题是我不知道他为什么不使用Port Forwarding。
private void SSHConnect()
{
PasswordConnectionInfo coninfo = new PasswordConnectionInfo(Settings.ReadSettings("sshhost"), Int32.Parse(Settings.ReadSettings("sshport")), Settings.ReadSettings("sshuid"), Settings.ReadSettings("sshpass"));
coninfo.Timeout = TimeSpan.FromSeconds(30);
client = new SshClient(coninfo);
client.Connect();
if (client.IsConnected)
{
Console.WriteLine("SSH is open");
}
else
{
Console.WriteLine("Error with SSH Connection");
}
var portFwdL = new ForwardedPortLocal(Settings.ReadSettings("ipa"), UInt32.Parse(Settings.ReadSettings("port")), Settings.ReadSettings("ipa"), UInt32.Parse(Settings.ReadSettings("port")));
client.AddForwardedPort(portFwdL);
portFwdL.Exception += delegate (object sender, ExceptionEventArgs e)
{
Console.WriteLine(e.Exception.ToString());
};
portFwdL.Start();
if (portFwdL.IsStarted)
{
Console.WriteLine("Port Forwarding starting");
}
else
{
Console.WriteLine("Port Forwarding failed");
}
